CHURN.

Specification of Letters Patent.

Patented Dec. 17,1912.

Application fi1ed April 13, 1912. Serial No. 690,607.

To all whom it may concern:

Be it known that I, NORMAN J. Tom, a subject of the King of Great Britain, residing at Mount Nebo, in the Province of Saskatchewan and Dominion of Canada, have invented new and useful Improvements in Churns, of which the following is a specification.

This invention relates to churns and means for operating the same, and it has for its object to provide a device of this class which shall be simple in construction and thoroughly efficient in operation.

WVith these and other ends in view which will readily appear as the nature of the invention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifica tions within the scope of the claims may be resorted to when desired.

In the drawing,-Figure 1 is a perspective view of a device constructed in accordance with the invention. Fig. 2 is a longitudinal vertical sectional view of the same, showing the churn supporting platform lowered for disconnection of the parts. Fig. 3 is a horizontal sectional detail view, enlarged, taken on the line 8-3 in Fig. 2. Fig. 4. is a sectional detail view, enlarged, showing the churn dasher connected with the operating mechanism.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame of the improved device includes the corner posts 1, l and an end post 2, said corner posts being connected together by a cap piece 3, which latter is connected with the end post 2 by a longitudinal brace bar 5. The corner posts 1, 1 afford bearings for a transverse shaft 6 carrying an eccentrio 7 that serves to support the rear end of a floor or platform 8, the front end of which is pivotally connected at 9 with the upright 2. The shaft 6 is provided with an arm or lever 10 whereby it may be oscillated.

A top piece 11 is suitably connected to the posts or uprights 1, 1 and 2 to which said top piece is made fast in any suitable manner.

The churn body 12 consists of a suitable cylindrical vessel which may be of earthenware or of any other suitable material, said vessel being provided with a tightly fitting cover 13 which is supported detachably thereon, said cover having a flange 14. overlapping the upper edge of the churn body. The cover 13 is provided with a sight opening 15 preferably covered with glass, as indicated at 16, and the cover also has a central opening or aperture 17 forming a bearing for the shaft 18 which constitutes the dasher stem or staff, said shaft being provided with wings or heaters 19. The upper end of the shaft 18 is detachably connected by a transverse pin or cotter 20 with the lower end of a shaft 21 which is supported for rotation in suitable bearings in the cross brace 5 and the top piece 11. Said shaft carries a pinion 22. Mounted for oscillation in the cross brace 5 and the top piece 11 adjacent to the end post 2 is a rock shaft 23 with which is associated a frame F including diverging side arms 24 and an arcuate rack bar 25, the latter engaging the pinion 22. The frame F is equipped with a handle 25, whereby it may be conveniently oscillated.

The top piece 11 is provided with a slot 26 to admit the dasher stem or shaft 18 when the churn is placed in position. The baseboard 8 is preferably provided with blocks or stop members 27 to engage the churn body for the purpose of sustaining the 'latter in proper position for operation. A

stop member 28 is also provided, the same lying in the path of the lever 10 to prevent the latter from moving beyond a predetermined point at which the eccentric 17 shall project upwardly from the shaft 6, thereby forcing the free end of the floor member 8 in an upward direction.

It will be readily seen from the foregoing description that when the lever 10 is moved in a downward and forward direction, the eccentric 7 will likewise be turned downward, thus lowering the free end of the baseboard 8. Assuming the connecting pin 20 to have been previously detached, it is obvious that the dasher stem will become disconnected from the shaft 21, thus enabling the churn to be moved out from under the top piece 11 and the lid or' cover 13 to be detached. On the other hand, when the parts are assembled, the churn is simply moved into position beneath the shaft 21 until it engages the stop members 27, after which the lever 10 is manipulated to elevate the floor member 8, thus compressing the churn body between the floor member and the top piece 11, which latter operates to force the churn lid 13 tightly in position where it is held during operation. By rocking or reciprocating the frame F, the churn dasher will be quickly rotated first in one and then in the opposite direction, thus causing the contents of the churn to be thoroughly stirred and agitated. The progress of the operation may be observed through the sight glass 16.

Having thus described the invention, what is claimed as new, is

1. In a device of the character described, a frame comprising corner posts and an end post, a top piece permanently connected with said posts and having a slot, a bottom platform pivotally connected with the end post, means for adjustably supporting the free end of the platform, and means for actuating the supporting means.

2. A frame including corner posts and an end post, a top piece permanently connected to said posts and having a slot, a bottom platform pivotally connected with the end post, a shaft supported for rotation upon the corner posts and having an eccentric member engaging and supporting the free end of the bottom platform, a churn body supported upon the bottom platform and having a loose lid, a dasher stem supported for rotation in the lid, means for actuating the eccentric shaft upon the corner posts to force the free end of the bottom platform supporting the churn body upwardly to clamp the lid between the churn body and the top piece, a dasher stem supported for rotation in the lid, and means upon the frame for operating the dasher stem;

3. In'a device of the character described, a frame including a stationary top piece and a movable bottom platform, a churn body supported upon the bottom platform, a lid upon the churn body, means for forcing the bottom platform in an upward direction to clamp the lid between the churn body and the top piece of the frame, a dasher stem supported for rotation in the lid, a shaft associated for rotation with the frame, means for connecting the dasher stem with the shaft, and means associated with the frame for oscillating the shaft.

4. In a device of the character described, a frame comprising corner posts and an end post, a cap piece connecting the corner posts, a brace member connecting said cap piece with the end post, a top plece permanently connected with the several posts and having a slot, a bottom platform pivotally connected with the end post, means associated with the corner posts to support the free end of the bottom platform for vertical movement, a churn body supported upon the bottom platform and having a lid, a dasher stem extending through the lid, a shaft supported for rotation upon the frame, means for detachably connecting said shaft with the dasher stem, a rock shaft connecting the top brace with the top piece of the frame, a frame associated with said rock shaft and including an arcuate rack bar, and a pinion upon the shaft connected with the dasher staff, said pinion being engaged by the arcuate rack bar.

In testimony whereof I aflix my signature in presence of two witnesses.
